How to Count Parrots: Comparing the Performance of Point and Transect Counts for Surveying Tasman Parakeets (Cyanoramphus cookii)

Diversity
Obtaining precise estimates of population size and trends through time is important for the effective management and conservation of threatened species. For parrots (Psittaciformes: Psittacidae), obtaining such estimates can be challenging, particularly ...

Genome Sequence of a Divergent Avian Metapneumovirus from a Monk Parakeet (Myiopsitta monachus). [PDF]

, 2019
Here, we report the coding-complete genome sequence of an avian metapneumovirus from a monk parakeet (Myiopsitta monachus), identified by metagenomic next-generation sequencing during an investigation into a disease outbreak in a captive parrot breeding ...

Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...

The prevalence of psittacine circovirus in native and exotic parrots in New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Conservation Biology at Massey University [PDF]

, 2005
Psittacine circovirus (PCV) has been identified in more than 60 psittacine species worldwide in both aviary and wild populations. The virus is a causative agent of psittacine circoviral disease (PCD), a highly infectious disease characterised by beak and

Large‐Bodied and Wide‐Beaked Avian Frugivores Show Greater Specialisation in Tropical Seed Dispersal Networks

Global Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Avian frugivores with large bodies and beaks are increasingly threatened due to smaller population sizes, greater energy requirements and higher vulnerability to hunting pressure and illegal wildlife trade. However, it remains unclear whether birds with these traits adopt consistent strategies in their interactions with fleshy‐fruited ...

Bird Beak Accuracy Assessment [PDF]

, 2003
The purpose of this resource is to quantitatively evaluate the accuracy of a classification system. Students sort birds into three possible classes based on each bird's beak: carnivores, herbivores, and omnivores.

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Sensory preferences and personality traits of captive red crowned kakariki (Cyanoramphus novaezelandiae) and Antipodes Island parakeets (C. unicolor) : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Zoology at Massey University, Palmerston North, New Zealand [PDF]

, 2017
The way in which most animals sense and interpret the environment around them differs from species to species. Even two closely related species such as the red-crowned parakeet (Cyanoramphus novaezelandiae) and the Antipodes Island parakeet (C. unicolor)

Extinction Risks of Tasmania's Avifauna

Journal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Globally, island biotas are continuing to experience catastrophic losses leading to species extinctions. In Australia, 31 bird taxa have become extinct since European colonisation, including four from Tasmania including Macquarie Island. In 2024, the Tasmanian Government's State of the Environment Report provided compelling evidence on the ...

Detection of Cryptosporidium and Giardia duodenalis in Reptiles in Thailand

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
ABSTRACT Cryptosporidium spp. and Giardia duodenalis are significant intestinal protozoan parasites affecting humans and animals worldwide. These infections are transmitted through the faecal–oral route, by contaminated water, food or close contact with infected hosts.
